Once you find a shop that you're considering, let them know you hang out on a detailing discussion forum where the problem of swirls in the paint is a common topic and you're looking for a shop that can fix the damage and return your car back to you without rotary buffer inflected swirls.
Ask them how they finish out? As in, what tool, pad and polish do they use and then come back here and post what you find out.
If the shop is up to date on doing quality work then it shouldn't bother them for you to ask these types of questions. My guess is that if they are not on top of their game then they're going to see you as a pain in the butt customer and won't feel like answering your questions, this too would be a sign.
You could also print out a few pictures or the entire article here and take it with you to show them what you're trying to avoid.
Better yet take a laptop or an iPad with the below thread bookmarked...
DISO = The Dealership Installed Swirl Option
Sad to say but all to often after you're car is "prepped" by the detail shop at some New and Used Car Dealerships, you get what we all call
DISO or the
Dealer Installed Swirl Option.
Although the term DISO is used to refer to dealerships the problem actually is connected to dealerships, body shops and yes... detail shops.
Keep in mind that if the body shop you go with does in fact swirl your car out, it might not show up until you wash it a few times to wash any polishing oils or glaze off the paint.
Then to undo the damage you'll have to re-buff the car the correct way and both their hack job of buffing and your repair job of buffing will remove precious clear paint that you just paid to have sprayed...
The term "Horror Story" is what we call the experience and results too many people get after having their car repaired and re-painted.
Good luck to you and let us know how this story plays out...
